Spectators can also see a pagoda perched atop a mountain in the distance, overlooking the industrial park.Views from the Shougang Industrial Park on Monday. (Selina Wang/CNN)What is big air? Skiers launch off a 60 meter-high (196-foot) ramp and are scored for the size, style and difficulty of their jump. Each competitor has three attempts to get the highest score possible.As each run is just one jump, skiers will throw down their biggest and best tricks in hope of Olympic glory.And unlike many of the mountain events, the stands are close to the action — giving the fans a front row seat.
